tiliAZTE id HENRY A. STENGER, 01F BOW'ELL, (LALITFGH-NIAH SELF'OILING BURIE -HEAD.

' To-aZZ whom it may concern 'Be it known that I, HENRY A. Srnuena, a

citizen of the United States, residing at Cowell, inthe county of Contra Costa and State of California, have invented certain new and useful Improvements in Self-iling Pump-Heads, of which the following-is a specification.

he primary object of this invention is to provide power transmitting mechanism for pumps arranged in the most compact form for communicating reciprocatory movement to the pump rod or similar operating member. r

One of the essential features of my invention is the formation of the pump head comprising this mechanism so as to insure-the proper lubrication of the operating elements with the least amount of attention and to this end said elements are disposed in a bath of lubricant making necessary the replenish- .ment of the supply thereof only at lengthy E intervals,

I centric rod connected /More specifically speaking my device com-- prehends the provision of a driving member having eccentric means formed thereon with which a lifting member cooprsates, anec to said lifting member, and means cooperating with the eccentric rod whereby to cause reciprocation of said rod upon actuation of the by the driving member aforesaid.

l/Vith the above and other objects in View, this invention consists in the construction,

combination and arrangement of parts allas hereinafter more fully described, claimed and illustrated in-the accompanying drawings, wherein Figure l is a side elevation of a pump head constructed in accordanceswith my in vention and showing in dotted lines the cooperation of the lifting member with the driving means therefor; Fig. 2 is a vertical section view taken about on the line 2-2 of Fig. 1; Fig. 3 is a side elevation of my pump head taken from "the""*sine cppssite that shown in Fig. 1;'Fig- 4 is a horizontal section view taken through the cover member for the pump head showing more clearly- Specification of Letters )Fatent Application filed December 13, 1913.

the construction of the guiding'r'neans for the eccentric rod, and Fig, 5 ,is a vertical sectional view through said cover member.

Specifically describing myinvention' and referring to the drawings, the numeral 1 designates a casting which is hollow in construction to form a for the pump head.

The numeral 3 represents the coverfor the casing 1, which element is shown most clearly in Figs. 3, 4 and 5,, respectively, of the drawings, and the pumprod which is to be operated by; the mechanism more specifically describedihereinafter. The rod 4 as shown in .the drawings is the type of rod usually employed in pumps and windmillsto which reciprocatory motion is usually imparted. Within the casing l is disposed a driving member or disk 5 to the outer periphery of which is secured the gear element 6, as by means of the fastening members or bolts 7. The gear member 6 meshes with a worm 8 on the casing, and the base power transmitting venient source of which forming no part of my invention, is shaft 9, is provided with suitable ball bearing-s10 and may be readily reversed in its connection with the driving gear 6 bythe removal of the sec tional' caps '11 and 11 suitably secured to the upper side portion of the casing 1 by fastening members 12. The. function ofthe reversibility of this shaft willbeevident to" in the art to which;this- -inven-" tion refers, it being necessary'atsltimes to" drive the mechanism from different; sides of the pump head. The disk 5 is formed on one face with 'a laterally projecting trunnion-13 journaled centrally of the casing 1 in the bearing i i-While onthe' opposite side of the disk are provided spaced flanges 15 formed eccentric to the axisv of said. disk. The flanges, as will be seen from Figs. 1 and 2-, form agroove 16 and in this groove is disposed ar'lifting mem-i her or ring 17 formed with a projecting stud l8. Pivotally connected to the stud 18'is provided an eccentric rod 19 whichsis adapt- 7 power such as amotor,

projecting laterally i ed to move vertically in the groove of the cover 3, and at the upper extremity said rod 19' is connected tothe pump rod & by the connecting block 21. As clearly shown in 1 Figs. 2 and 5 the cover plate is formed at its upper and lower portions with apertured projections 22 in which the pump rod l is adapted to reciprocate.

As hereinbel'ore stated one of the advantageous features of my construction is the formation of the casing l or punip head so as to contain a. lubricant which is supplied.

to the hollow interior oji said casing by the removal of a plug 23, and said lubricant may be Withdrawn from the casing 1 through the instrurnentalityef the pet-cock 24: disposed at the lowermost portion of said casing.

' rod 19.

the top portion of the groove is reamed out as shown most clearly in Fig. 5 oi the dran ings and indicated by the numeral. 26. An oil groove 27 leads from this point to the .upper apertured. projection 22 so that the pump rod l is effectively lubricated at this point by the surplus oil working up the It Will; he obvious from the foregoing that the mechanism may be driven at any suitable speed and any desired amount of reciprocator'y movement may be imparted to a pump rod by the proper. proportioning of the parts of my invention ccnnectedthcreith. The driving shaft driven from a convenient source of power causes the disk 5 through the "instrumentality of the gear member 6 torotate about the axis of said disk, and the lifting member 1? disposed in. the groove 16 gradually moves around. in said groove lifting the eccentric rod ,19 which is guided by the cover 3 so as to cause said rod to reciprocate and impart similar -m0tionto pump rod i. It will be apparent that such reciprocal motion oi the eccentric rod 19 is permitted the pivotal. connection of the same on'thc stud 18 carried by the littingring, said. stud moving a true vertical plane right angles to the axis of. i 731 ct dislrv .us described invention what new i1cad con? claimed secured to the periphery of said disk, driving means for rotating said disk, a lifting ring disposed in the groove of said disk and having a projection extending therefrom, an eccentricrod pivotally connected to the pro jection, and cover for said casing having a groove formed therein which said eccentric rod is adapted to reciprocate Whereby to maintain the said rod in rigid operative position during actuation thereof:
